VENTILATIYNG WINDOW FOR PASSENGER CARS AND THE LKE.

Application filed February 18, 1922. Serial No. 537,435.

To all whom t 'may concern.'

Be it known that l, HIRAM BRUCE TROUT, a citizen of the United States,residing at Mattoon, in the county of Coles and State of Illinois, haveinvented certain new and useful improvements in Ventilating `Wind0ws forPassenger Cars and the like; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

T his invention relates to improvements in Ventilating apparatus, andmore particularly to such as are especially adapted for use on vehicles,such as railway cars and the like.

The obj-ect in View is the facilitating of the admission or circulationof air under conditions assuring both the effective control of thequantity of air circulated and the physical condition of the airregardingfreedom from dust, cinders, and other foreign substances.

A further object in View is the arrangement of the invention in suchform as to be applicable to railway cars already in use as well as tonew ones.

Another object in view is the provision of means for easily and readilyvarying the air intake according to the direction of travel.

With these and further objects in view as will in part hereinafterbecome apparent and in part be stated, the invention comprises certainnovel constructions, combinations and quently specified and claimed.

ln the accompanying drawings,

Figure 1 is a view in side elevation of a fragment of a railway carequipped with an embodiment of the present invention and viewed from theinside of the car.

Figure 2 is a vertical section therethrough taken on the plane indicatedby line 2-2 of Figure 1, parts being seen in elevation and the car seatbeing omitted.

Figure 3 is a perspective view of the ventilating apparatus detached.

Figure 1 is a vert-ical section taken on the plane indicated by line 1-4 of Figure 1.

Figure 5 is a horizontal section taken on the planes indicated by line5-5 of Figure l and looking downward, the parts being in the positionshown in Figures 3 and 1.

Figure 6 is a similar section of the same with the window shown closed.

Figure 7 is an enlarged, detail, fragmenarrangements of parts as subse-lguiar position,

tary section of a corner portion of the parts as seen in Figure 6.

Figure 8 is an enlarged, detail, fragmentary, vertical section taken onthe plane indicated by line 8-8 of Figure 5.

Referring to the drawings by numerals, 1 indicates the side wall of arailway coach or other vehicle having the usual intramural space 2 abovethe window opening 3, and having a framing l surrounding the space 2 andopening 3, and provided with vertical grooves or other appropriateguidesr4 5 for receiving the beads or other cooperating guides 6, 6, onthe window sash 7. The sash 7 is rectangular, or otherwise shaped, toconform to and is slightly larger than the window opening 3, and isadapted to slide up into and down out of the space 2 from and to aposition closing the window opening 3. The sash 7 is provided with aneye, or other appropriate anchoring means, 8, to which is connected acoiled spring or other suitable counter-balance 9, anchored at its upperend to the frame 4 for facilitating movement of the frame 7 Vupward toenable the passage of bedding or hose, or the permitting of a passengerto move through the window opening in the event of a wreck without thenecessity for breaking the glass of the window hereinafter referred to.A handle 10 facilitates manual manipulation of the sash 7.

A glass-carrying frame 11 is arranged to move within the sash 7, and isproportioned vertically to lit snugly against the horizontal plates ofsash 7, but is of sufficiently less width to provide spaces 12, 12,between the vertical plates of the sash 7 and the side walls of theframe 11, whereby the frame 11 is free to rock to and from a skewed oransuch as shown in Figures 3, l and 5. The frame 11 is a boxing, eachplate of which boxing is equal in width ap, proximately to the width ofthe adjacent plate of sash 7, and the side walls or plates of frame 11are each made up of vertical strips connected by a screen, or otherlappropriate filter, 13. To the outer edge of the boxing, constitutingthe frame 11, there is xed the molding 111which is preferably of thehollow type, usually formed of metal, and arranged to carry the panes ofglass 15, 15, there being two panes for the added protection afforded bythe dual glass as now customarily employed in railway car con.struction. .A cushioning pad of rubber, felt,

or other appropriate material, 16, is arranged between the panes 151erinsuring their effective retentionin the molding 14.

The inner edge portions of the `upper and Figures and 6, and has thecentral portion vofthe bow arranged beyond the respective-lug 19, theend portons of each rod l18 being slidingly extended into sockets l 20formedin the respective horizontal walls of -frame 11, and the rods 18being tensioned,-when being assembled, so as to be lunder tension whenin the position seen in Figure 6. Thus the frame V11,'when free to doso, seats itselfnaturally in its inward position, as seen in Figure 6,and remains 1n g that'position until otherwise moved. To

prevent 'friction and noise, the outer edge of the sash 7 is preferablylined with a cushion 21 against which the inneriface of moldina 14 restsunder'the tension oi spring 18. Approximately midwayin thelength of theinner edgeportion of each of the vertical walls lof frame 11 there isprovided a longitudinalnotch 22 in which lies an operating arm` 23,fixed to a rock shaft 2%1 j'ournaled in thevsash 7, and extending.through and also j'ournaled in a housing 25 vliereinaier described. Tofthe projecting inner end of eachshaft 24 is connected an operatingcrank 2 6 for facilitating manual manipulation of the frame 11, itbein-g apparent that when either of the shafts 24 is moved angularly bythe-action of the respective crank 26, the respective arm 23 will beswung vertically to the position seen at the righthand side of Figure 5,whereby the arm 23 engaging the frame 11 in notch 22 moves the 'frame tothe outer position seen in Figure 5. ThisV angular or tilted position ismade possible oil attainmentby. the framell by virtue of its loose iitincident to the lspaces 12, the frame moving out pivotally on the lineot Contact of the molding 141 with the vertical edge of sash? mostremote from the particular shaft y24e and arm y23 being manipulated.Thus the opening covered by the respective screen 1.3 is exposed forladmitting air kto the interior of the car. It will be obvious, ofcourse, that the frame 11 will be re-seatedby .the action of springs-1 8as soon as the respective arm 28 is returned to its lowered position,andl .it will also be ap-v parent that, when desired, both of thearms 23may be swung to their horizontal position at the same time,`and thewhole iframe 11 .will thus be moved outward against the action ofsprings 18; whereby the side openings of both oit the vertical sides ofthe trame llwill be exposed. Thus the edge opening of trame 18 `at etheredge may be exposed, according to the direction'ot' travel of the carfor freely admitting air, and the frame may be adjusted easily andquickly for reversing its .relation to the balance of the structure soas to expose the other opening when the car is caused .to movein theopposite direct-ion, this being accom-V plished by the manipulation otthe operatingleversf26. To prevent the collection ot cinders and otherforeign substances on the upper surface of the 'frame 11, whenextended,a hood 27 is xed to the wall 1 and outstands therefrom adistance su'liieient to enclose and cover the frame v11 in any of itspositions.

T the shafts 24- were adequately journaled in the sash 7, or otherwisesuitably rotatably connected therewith,the-parts would unction asdescribed without the presence of 90 the housing 25, but therewould'beo'pportunity for leakage through one or Ithe other of theopenings 12and, therefore, I provide a framelike housing 25 whichextends about theinner edge of the sash 7 and is 95 fixed thereto. Thehousing outstands from the wall of the sash and isformed at an abruptangle to extend` about the frame 11 so ast'o completely conceal the samefrom i observation from within the car, while leaving the frame tree tomove in the space between the housing`25 andthe .sash Thus, whileguarding effectively against leakage of dust, or other foreignsubstance, the frame l 11 is freely andVv easily manipulated Aeither 105by apassenger .or an oiiicial by the operation of the levers 26, and theparts at the same time are given the finished' appea-rancezot theordinary window.: It will alsobe ob# served that when one of the levers26 is erp-"110 erated, it is moved to the vposition indicated in Figure5, wherein the arm 23 is above the line of the axis ofmovement, havingmoved 'from the pendant position, as seen in Figure Ll. The pressure ofsprings 18, tending'to 115 restore frame 11, will'causethe'arm 23 to bepressed in its raised' positionfagainst the terminus of the recess 22,whereby the frame 11 is locked in its adjustedv position and will remainthere until released'byr the 120 manual lowering of theyrespective'lever 26.` l/Vhat is claimed is f i 1.
